1. Why is it better to have only 2 choices at each step instead of more?
You have a 50/50 chance of getting the candy name right if you only have 2, and it makes things easier to narrow down the choices.
2. What problems did you encounter in using the dichotomous key? Be specific and discuss fully.
The fire ball and the jaw buster matched the same description and it was more difficult to find the correct name.
3. How did you resolve your problems in #2?
We went back and looked at our names again, and looked over the clues better.
4. Do classification keys go from general to specific characteristics or from specific to general characteristics? Explain why.
Classification keys go to general to specific characteristics, because at first it goes from chewy to hard and then it goes to specific colors of wrappers.
5. What does the first and second part of the Latin name represent in the scientific name of the organism?
The first part of the Latin name is the genus and the second part is the species which represent in the scientific name of the organism.
6. Research Carolus Linnaeus and his contribution to modern classification.
Carolus Linneaus contribution to modern classification is that he laid the foundation of the modern scheme of taxonomy.
7. What is a dichotomous key? (define)
A dichotomous key is a tool that allows the user to determine the identify of items in the natural world, such as trees, willdflowers, mammals. Key consist of series of choices that lead the user to the correct name of a given item. "Dived into two parts" means "Dichotomous". The Dichotomous key always gives you two choices in each step.
8. What is binomial nomenclature? (define)
Binomial nomenclature is the system used to idenify all organisms on Earth, from elephants to algae.
9. Briefly describe how classification has changed before and after Linnaeus. Research Aristotle...
Aristotle presented his own arguments and solutions.
10. List the order of classification groups from Kingdom down to species.
Kingdom: Animalia
Phylum: Chordata
Subphylum: Vegebrata
Superclass: Gnathostomata
Class: Mammalia
Order: Primata
Suborder: Haplorhini
Family: Homindae
Genus: Homo
Species: Homo Sapiens
Seed Lab Plants
Homeostasis Lab
Procedure: For the Homeostasis Lab, there was a running exercise where she ran around the block downstairs. Amanda Brubaker would run around the hall for two minutes at four intervoles. Then after every run, she would get her blood pressure, pulse, and temperature taken.

25 Degrees Celsius
Conclusion: In conclusion, her heart rate increased 86 to 137 then decreased to 112 and then increased to 126 over the time of 8 minutes. Amanda's temperature stayed similar throughout except the time of two minutes.Her blood pressure kept going up until the sixth minute when it dropped but then began to go up again in the eight minute, causing us to think that there might have been in error. In the beginning her face was a rosey red color, then after 2 minutes of running it turned very pale. The reason for this lab is because it is showing how we can mess with our homeostasis, and how it makes our body function different.
Temperature and Pulse Graph:
Blood Pressure Graph
Analysis:
1. What are the changes that you observed throughout the experiment?
Amanda's heart rate, blood pressure, pulse, temperature, and the color of her face changed through out the experiment.
2. How do each of those changes help the body adjust to maintain equilibrium (homeostasis)?
It make your body work faster and helps your body burn more energy.
3. What mechanisms are used to maintain body temperature in the body?
Sweat and sweat glands.
4. What is the purpose for an increased respiratory rate and heart rate?
It helps you breath and cools down your body to a good temperature.
5. Write a paragraph about the conclusions you can draw about your body's ability to maintain equilibrium (homeostasis.) Be sure to discuss some of the information from your other answers.
That your body sweats more you heart beat rises your breathing increase and your temperature goes up.
Protists
1. Name: Volvox
Autotroph or heterotroph: heterotroph
Where found/facts: its a genus of fresh water, chlorophyll-containing green algae. Found in ponds, ditches, even in shallow puddles. It is the most developed in a series of genera from from spherical colonies.
Resource listed: http://www.britannica.com/EBchecked/topic/632669/Volvox - http://en.wikipedia.org/wiki/Volvox
2. Name: Daphnia
Autotroph or heterotroph: Dapnia's are heterotrophs.
Where found/facts:lakes and ponds found in Ireland also any like or pond lime based is the best to find them at.
Resources: http://www.caudata.org/daphnia/#what3
Stentor Coeruleus
It is a heterotroph because it feeds on bacteria. https://wiki.answers.com
It is found in fresh water. It is either free-swimming ,or attached to submerged vegetation http://www.britannica.com
It is an oval or pear shape while swimming. The bigger end has ciliary membranelles around the area that leads to is mouth. It uses these cilia to pick up food into its cytostome. http://www.britannica.com
